Thanks John, I've been googling and I've also came across some GSM
remote controls used to swith on - for example - heaters in an holiday
house or open gates, though they are expansive (also because they do
much more than I need), and not as fun at all! :-)

I still hope for yours and other's suggestions. Thanks.
